Konstruktion och undersökning av effektsnåla slumptalsgeneratorer

Minskad effektförbrukning har blivit mer och mer intressant i takt med att fler produkter blir mobila. I artikeln Parallel Implementation of Linear Feedback Shift Registers for Low Power Applications, beskriver Menahem Lowy en metod för att konstruera slumptalsgeneratorer. Dessa är tänkta att vara effektsnålare än en vanlig enkel slumptalsgenerator, med återkopplat skiftregister. I det här examensarbetet har sex slumptalsgeneratorer konstruerats i VHDL. Två är baserade på Lowy?s metod och två är parallella varianter av dessa.

?TOMMA HUS ALLAS HUS? - En studie om husockupationer

The purpose of this thesis is to investigate the relationship between urban transformation and the occupation movement in Sweden, aiming to identify the movement's characteristics and comprehend its changes over time. By analyzing qualitative material collected from occupants active within a span from the 1980 to the present, we examine how the occupation movement has evolved. We investigate the motivations behind the movement, the lifestyle of occupants, and their potential gains to get a better understanding of the culture. We explore the prefigurative politics of the resistance where occupant activists create alternative lifestyles aligned with their desired future, bypassing the wait for broader societal changes. Finally we inquire the current possibilities of creating and defending meaningful urban spaces and social scenes..

Läsa spel. En analys av Alice-böckernas adaptation till spelformatet

The purpose of this essay is to examine the consequences following an adaptation from literature to video game formatby comparing Alice's Adventures in Wonderland and Through the Looking Glass with American McGee's Alice and,primarily, Alice: Madness Returns. In order to answer this, aspects of both game theory and literary critique are takeninto consideration, regarding for example the narrative potential of the game medium and the gameplay's possibleresemblance with Wolfgang Iser's theory of the reading process.The analysis shows in what ways the original narrative has been altered in order to fit its new medium. Some of thebooks' main ingredients are simply retold in the games' so called information spaces, i.e. text and video sequenceswhere the otherwise playable character is not controlled. Others, instead, have undergone a ludolization or ergodizationwhere the story events are experienced as playable elements in the games' action spaces.

Ljud i landskapsarkitektur : från buller till kvalitet

Landscape architects has many ways of transforming our cities and landscapes. Traditionally, most attention has been put to visual qualities. Pen and paper are well established as the way to present proposals and to analyse in the landscape architects profession and training. But are we perhaps missing out on other ways of seeing the landscape? The purpose of this paper is to present sound as a tool of transformation. Sound in public spaces has long been treated just as noise and therefore unwanted.

Från militärområde till stadspuls : Stadsdel Norr - en (nästan) vit fläck på Östersunds stadskarta

How can former military area I5 in Östersund, Sweden, evolve into Stadsdel Norr ("The Northern Quarter") ? an attractive part of the town center? In a theoretical part of the essay the significants of well functioning towns and streets are investigated. The history of Östersund and I5 is shortly reviewed. Present recommendations concerning city design are presented along with guidelines from Vägverket (National Road Administration) for urban streets. The conclusion reached is that a fundamental structure of streets and roads, public and private spaces, is crucial for the possible future development of an area.

Demonstrationsprojektets roll i framväxten av ny teknik: Fallstudier av två vindkraftprojekt

This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.

Vilka faktorer påverkar företags kassahållning?: En studie av svenska börsbolag 1999 - 2009

This paper investigates the determinants of corporate cash holdings for a broad sample of Swedish non-financial firms in the 1999 - 2009 period. Using a fixed effect regression model, we find that firms with riskier cash flow hold relatively high ratios of cash to total assets. This is in line with both the precautionary motive and agency motive for cash holdings. Net working capital is found to be negatively related to corporate cash holdings. A result commonly interpreted as support for a negative substitution effect between net working capital and cash.

Design och oro : En studie om inredning och möbeldesign och dess möjligheter att minska oro hos dementa

Between 1999 and 2009, I followed three of my grandparents, all of whom suffered from dementia. Numerous times, when I visited them in their nursing homes, I was met by residents of the ward who were very unhappy. Through conversations at home with my family, I understood more and more that this was a commonly occurring problem at nursing homes. All too often it was solved with heavy medication, which made the residents tired and they slept more often.During my undergraduate education at Konstfack, I have reflected on whether I, as an interior designer and furniture designer, can have an influence on spaces and furniture so that dementia patients can experience greater calm and security. The idea is if that I perceive the environment as calm and secure, I will also be calm and secure.In my degree project, I want to study how interior design and furniture design can contribute to decreased agitation in people with dementia in nursing homes..

Adaptiv katalysatormodell för reglering

This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.

Studentbostäder i trä med Prefab-teknik

The Results of this thesis was the creation of two designed house variants with a module toall the apartments. In addition till the first module there are three other modules ofapartments that can be put in the houses if it so needs. The house are volume prefabricatedand are placed on site in a way that it create an enclosure of the area which faces against thenature and car parks also lies hidden behind these houses.For the actual structure, a cross beam was created to carry the floor above and it is supportby all four walls. The structure between the first and the second floor has no "syll" butinstead there are two differently alternative to linking the floors in order so that it will notmove. The reason with this solution was that there will not be any subsidence when theforces from above are pressed down ward.

Skuldlättnader som vapen i kampen mot korruption? : Om hur HIPC-initiativet påverkar korruptionsgraden i berörda länder

This paper examines how debt cancellation, given under the HIPC-initiative, has affected corruption over the period 2000-2006. The examination is foremost interesting due to earlier research showing that high corruption leads to unequal distribution of economic resources. This, combined with the objective of the HIPC initiative to reduce poverty, indicates that combating corruption must be successful in order to fulfill the goals of the initiative. A linear regression shows that countries that have benefited from the HIPC-initiative indeed have a lower corruption than other countries. A panel-data analysis shows on the other hand that no effect on corruption due to debt cancellation or reforms undertaken in the program can be confirmed..

Lekens betydelse för barns utveckling : En studie om hur skolgårdsmiljöns utformning påverkar barns leklust

The purpose of this study is to illustrate the impact on children's development around playing and how significance the formation of the schoolyards is focusing on how it inspire and calls to play within the children's. The study will also show how the youth workers experience the schoolyards and how they can incorporate the playground in their work to inspire the children's play and activities. The methods used in this study is based on both real conversations and by mail with educated youth workers and observations. The results shows that the schoolyard environment is very important for the children's play and development. The study reveals the importance of having nature like forest nearby and that the environment should be suited for everyone.

Effekter av predationsrisk på sånglärkors (Alauda arvensis) habitatval på åkermark

Along with other European farmland birds, the skylark (Alauda arvensis) has declined rapidly since the 1970?s. Between 1975 and 2003, the Swedish population of skylarks declined with 64 %. In Britain, the decline is often explained by alterations in farming practices in general and the shift from spring-sown to winter-sown cereals in particular. The dense vegetation structure of winter cereals is limiting the number of breeding attempts possible, causing the entire population to decline.
